Introduction

In this ESP8266 tutorial we will check how to mount the ESP8266 SPIFFS file system, using the Arduino core.

SPIFFS was selected as the file system of the ESP8266 to accommodate the constraints o the device, including the limited RAM [1]. You can read more about the ESP8266 file system here. You can also learn more about SPIFFS here.

In this introductory tutorial we will only check how to mount the SPIFFS file system. Nonetheless, this is a very important procedure since we need to execute it before we use any other SPIFFS file system function [1].
